I had a carpeted area in front of my desk and I was ruining the rug by rolling over the edge of the persian rug. The mat immediately solved the problem. The area under my desk is wood and the mat had no problem transitioning from the rug to the wood. It looks and feels robust and I am confident that I will get several years of use out of the mat. Your catalog should give the thickness of the mat and the lengths of the pegs that grip the rug (I would estimate the grip peg lengths as 1/8" and the thickness as 3/32")
I am using this mat on a low pile carpet with a thick carpet pad. My problem is that the mat dents into the cushioned floor covering and then my chair wants to roll and "stick" where those dents are so maybe a thicker mat would have been better but I was also looking for affordability (as in cheap). So I got what I paid for. I don't know that I would recommend for use on home carpeting.
I had a plastic protector before which did the job but it wore out. This product is aggravating and fairly useless. I WOULD recommend it to an enemy but not to a friend.
